If we ever want three or more aliases, at that point we should put MSVC
warning ids in DiagnosticGroups.td. We can use that to support #pragma
warning.

This is consistent with -Wbuiltin-macro-redefined, and puts this common
extension warning under a flag.

Seems getSomething() is more common naming scheme than just a noun
to get something, so renaming these members.

Atoms with deadStripNever attribute has already been added to the
dead strip root set at end of Resolver::doDefinedAtom, so no need
to check it for each atom again.

Removes unnecessary casts from non-generic address spaces to the generic address
space for certain code patterns.

ELFLinkingContext has a method addUndefinedAtomsFromSharedLibrary().
The method is being used to skip a shared library within --start-group
and --end-group if it's not the first iteration of the group.
We have the same, incomplete mechanism to skip a shared library within
a group too. That's implemented in ELFFileNode. It's intended to not
return a shared library on the second or further iterations in the
first place. This mechanism is preferred over
addUndefinedAtomsFromSharedLibrary because the policy is implemented
in Input Graph -- that's what Input Graph is for.
This patch removes the dupluicate feature and fixes ELFFileNode.

When rematerializing through truncates, the coalescer may produce instructions
with dead defs, but live implicit-defs of subregs:
E.g.
%X1<def,dead> = MOVi64imm 2, %W1<imp-def>; %X1:GPR64, %W1:GPR32
These instructions are live, and their definitions should not be rewritten.

"x.empty()" is more idiomatic than "x.size() == 0". This patch is to
add such method and use it in LLD.

Reversed the order in which LD_LIBRARY_PATH is defined in order to make sure the
${CLOOG_INSTALL} prefix is found first.

By ignoring this pragma with a warning, we're essentially miscompiling
the user's program. WebKit / Blink use this pragma to disable dynamic
initialization and finalization of some static data, and running the
dtors crashes the program.
Error out for now, so that /fallback compiles the TU correctly with
MSVC. This pragma should be implemented some time this month, and we
can remove this hack.
